To all whom 'it may concern;

Beit known that I, JOSEPH V. HuLL, a citizen of the United States, and aresident of Brooklyn, in the county of Kings and State ofNew York, haveinvented certain new and useful Improvements in Closures for. Bottles,Jars, and other Receptacles, of which the following is a The inventionrelates to improvements in closures for bottles,jarsandotherreceptacles; and it consists in the novel featureshereinafter described, and particularly pointed out in the claims.

Theinvention comprises, in its preferred form, a ca I to be applied overthe mouth of a bottle or the like and having its lower edges bentoutwardly and then downwardly into right angular form producing abeading containing an annular outwardly projecting recess to receive apacking-ring in line with an annular shoulder I ready removal of theclosure.

formed on the bottle neck, and a removable lockingring of angularformation in cross section adapted to the annular beading on the cap andcooperating therewith in securing the said packing, the latter beingheld by the'walls of said ring and said beading, and the lower outeredges of said beading being formed with tongues adapted, during theapplication of the closure, and the vertical compression of the packing,to be pressed inwardly below said locking-ring and effect the'firmsecuring together of said cap and ring in opposition to the resistancecreated by the packing. The aforesaid tongues will preferably haveextensions or finger-pieces leftfree of the surrounding parts to begrasped and pulled outwardly in a lateral direction from thelocking-ring whenit is desired to unseal the bottle and remove the cap.The sealing of the receptacle is accomplished by, forcing thelocking-ring in a direction toward the annular projecting portion orbeading of the cap and against the packing ring, the latter reingthereby squeezed laterally against the bottle 11 ck and thelockingtongues being folded inwardly beldw' the locking-ring so as toeffectually lock said cap and ring to-' gether and enable them to resistthe outward pressure exerted by the packing-ring. i

The object of the present invention is to profvide an effectual two-partcap or closure which may be conveniently applied to and removed fr. mthe bottle or other receptacle, and hence it is that during thecompression of the packing ring toseal the bottle the locking-tonguesare made to effectually tie the cap and locking-ring together and areleft in such exposed position and condition that they maybe convenientlyturned back from their locking position tofree the cap and locking-ringfrom eachother and permit of the The invention will be fully understoodfrom the detailed description hereinafter presented, reference being hadto the accompanying drawings,'in which:

Figure 1 is a bottom view, partly broken away, of a closure. embodyingmy invention, the parts being shown in the relation they bear to bneanother prior to the compression of the packing ring; Fig. 2 is avertical section of same on the dotted line 2-2 of Fig. 1; Fig. 3 is aview corresponding with Fig. 2 but illustrating the closure as appliedto a jar, with the parts of the closure shown in the relation theyoccupy to one another after the vertical compression of the packing ringto effect the sealing; Fig. 4 is a detached top view of the lockingringwhich cooperates with the cap; Fig. 5 is a vertical section of saine onthe dotted line 5.-5 of Fig. 4; Fig. 6 is an enlarged view reproducingthe left-hand portion of Fig.2 and illustrating the relation of theparts of the closure prior to the compression of the packing-ring; Fig.7 is a like view of the righthand portion of Fig. 3 showing the relationof the parts after the vertical compression of the packing-ring andapplication of the closure to the neck of a receptacle, and Figs. 8 and9 are views corresponding with Figs. 6 and 7 but illustrate a modifiedform of the invention, Fig. 8 showing the relation of the parts beforethe vertical compression of the packing-ring, and Fig. 9 the relation ofthe parts after such compression.

- The closure comprises a cap 10, locking-ring 11 and elasticpacking-ring 12, and said cap is formed with a top 13, sides 14 andannular right-angular projecting portion or beading created by theoutwardlyand downwardlyextending parts 15, 16 at the loweredgesof'saidsides. The locking-ring llisof right-angular formation- Inthe construction shown inFigs. 1 to 7 inclusive,

the lower edges of the angular beading on the cap is formed with aseries of locking-tongues 19, and the locking-ring 11 fits within thevertical sides 16 of said beading, as shown in Figs. 6 and'7,'said sides16 and the vertical sides of said ring 11 being about equal in extent sothat after the vertical compression ofthe packing 12 the upper edge ofthe locking-ring may about reach the horizontal portion 15 of the capand said sides of saidbeading and locking-ring form a uniform doublethickness, as shown in. Fig. 7. In assembling the parts, the packing 12'may be placed upon the ring 11 and therewithintroduced to the beading ofthe cap, the locking tongues 15) being bent inwardly to a limited extentbelow thelockingring 11, as shown in Figs. 2 and 6, to hold the partstogether without at-such time compressing the packing.

- bottle, the sealing will be effected by pressure appliedsides 14 ofthe cap and the inner vertical edges .ofthe horizontal portion of thering 11 stand outwardly fromsaid edges of said packing, as shown in Fig.6.. The parts having been assembled, the closure may be introduced uponthe neck of the .bottle or receptacle 17 and then subjected to furthertreatment for sealing thev latter. After-the closure has been placedupon the 4 vertically against the lower horizontal surfaces of thelocking ring 11 to compress thef'packing 12, while at the same time thetop, sidesiandannular beading of the cap are held within .a closelyfitting socket in the capping-machineand prevented from expanding orbecomi-ng distorted, the effect of the vertical pressure applied againstthe locking ring 11 being that the said ring will be forced upwardlyfrom the position in which it is illustrated in Fig. 6 to that shown inFig. 7, and that the packing 12 will becompressedand squeezed outwardlyagainst the neck of the bottle, a portion of the .packing passing fromthe annular beading and against the .bottle neck andextending.partlyaboveandpartly below the shoulder 18 on said neck.During the compression of the packing the locking-tongues 19 are forcedinwardly along the lower surfaces of the lockingsring .11. After thevertical compression of the packing has I taken place the lower edges ofthe sides 16 of the beading-on the cap will be found to have reached thelower edges of the locking-ring 11,as shown in Fig. 7, and thus thelocking tongues 19 are permitted to be folded inwardly against theentire width of. said ring, with a suitable portion of said tonguesextending downwardly to form finger-pieces 20 for use in unsealing thebottle. The tool for compressing the packing-ring to effect the sealingwill engage the entire lowersurface of the .locking-ring 11 between thetongues 19 and during this compression the tongues 19 will be bentinwardly be- .low the locking ring, so that upon the removal of thebottle from the capping-machine, said tongues may be .relied upon formaintaining the ring 11 in position against the. compressed packing.After the bottle has been sealed the beading on the cap will be composedof the parts 15, 16 and locking ring 11, the. latter becoming locked tothe cap and forming a continuation of the heading. I

Whenit is desired to remove the cap from the battle the finger pieces 20will be grasped and pulled outwardly to bend the locking-tongues 19 frombelow the ring 11, this having the effect of enabling the packing toforce the ring 11 downwardly and thereby free itself from sealingcontact with the bottle neck, after which the cap may be lifted from-thebottle.

' It will be observed upon reference to Fig. 7 that the lower edgesofthe sides 16 of the heading do not fold under the locking-ring 11 butthat only the fingers 19 pass below said ring, the purpose of this beingto enable the ready and convenient unsealing of the bottle by simplypulling outwardly upon the locking-tongues 19.

In Figs. 8 and 9 1 illustrate a'medified construction of a portion ofthe invention in which I provide a locking-ring 21 to fit upon theexterior of the sides 16 of the beading on the cap and form saidlocking-ring with locking-tongues 22 extending upwardly to lap andfinally lock upon the upper surfaces of said beading, said tongues 22being provided with finger pieces 23 adapted to be graspedin the act ofpulling the tongues outwardly from the cap for unsealing the bottle. 1nthe construction shown in Figs. -8 and 9 the vertical sides. ofthebeading are of about the same extent as the vertical sides of thelocking-ring, and when in the act of'sealing the bottle the lockingring'is pressed upwardly to compress the packing 12, only the tongues 22will be forced inwardly upon the upper surface of v the beading, hencethe unsealing of the bottle may be readily accomplished by simplypulling said tongues outwardly to'permit the packing to force the ring21 downwardly and release itself from binding engagement with the'bottleneck. I In both of the constructions presented, the locking tongues areof snfficient'length to lap inwardly, when ,the bottle is sealed, toaconsiderable extent upon that side of the beading atwhichthey may belocated,

in Fig. 7 at the lower side of the beading and in Fig. 9 g

at the upper side thereof, whereby the parts become verysecurelyfastened together and the bottle firmly sealed. One-feature ofthe-present invention is to.

render it convenient to unseal the bottle without the i use of specialtools and removethe 'cap therefrom, and in carrying out this feature ofthe invention leave theends or-finger pieces'of the locking-tongues 19in such exposed position that they maybe readily engaged or taken holdof for turning the tongues back from: their locking position, this aloneenabling the packing to free itself from its sea'lingcondition andpermit the removal ofthe cap.

What I claim as my invention and desire to secure by Letters-Patent, is:

1. A closurecomprising a cap member having at the lower edges of itssides' an annular projection or beading formed by carrying the metaloutwardly and downwardly, a packingring within said heading, .and alocking-ring member having lower portion to engage said packing andvertical sides adapted to the sides of said beading, one of said membersbeing formed \vith .lockin g-tongues to be folded inwardly upon theheading when the packing is compressed therein to effect the sealing,and said tongues when forced outwardly permitting said packing to freeitself from ltsscaling condition and said cap to be re moved;substantially as setforth. i

2 A closure comprising a cap member having at th lower edges of itssides an annular projection or beading formed by carryingthe metaloutwardly and downwardly, a packingwingwithin said bending, and alocking-ring member-having alower portion'to engage said packing andvertical sides adapted to the sides of said beading, one

of said members being formed with locking-tongues to be folded inwardlyupon the heading when, the packing is lug locking-tongues, apa ckingring within said beading, .and a'locklng-rlng having a lower portion toengage said packing and vertical sides adapted to the sides o f'saldbeading, said 'tongue's upon the vertical compressiouof said packing toeffect the sealing being-adapted to be.

.folded inwardly against said locking ring for binding the same againstthe compressed packing, and said tongues when forced outwardlypermitting. said packing to free itself from ltsscaling condition andsaid cap to be. removed; substantially as set forth. I v

' 4. A closure comprising a cap-having, at .the lower edges of its sidesan annulamprojection or beadlng formed by carrying the metal outwardlyand downwardly and the said beading having at its lower edges downwardlyextending locking-tongues, a packing ring within said beading, and alocking-rlng having-:1 lower portion to engage said packing and verticalsides adapted to the sides of said beading, said tongues upon thevertical compression of said packing to efiect the sealing being adaptedto be folded inwardly against said locking-ring for binding the sameagainst the compressed packing and to leave pro- 10 jecting portionsthereof exposed to constitute finger-pieces,

and said tongues when forced outwardly permitting said packing to freeitself from its sealing condition and said cap to be removed;substantially as 'set forth.
